To all whom it may concern.-

Be it known that 1, WILLIAM E. BALDWIN, a citizen of the United States, and resident of the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful llmprovements in Books, of which the following is a specification.

My invention relates to books of the type having a permanent body of leaves bound between covers and adapted tohave a su plement in the form of a pamphlet, note 00k, or the like, inserted between one of the cover members of the book and the body of permanent leaves.

One of the objects of the invention is to provide a book of this type of sturdy, duraole construction which will present a neat, trim appearancawith all of its edges true and without slack in the binding when the supplement is removed.

Another object of the invention is the provision of a book of this type having a structure adhering as nearly as possible to that of a book ofstandard form and adapted to be manufactured by the standard methods of book-binding.

In the drawings:

Figure 1 is a perspective view of the book with one of the cover members opened and the supplement rempved;

Fig. 2 a similar view of a portion of the book upon a larger scale;

Fig. 3 a view similar to Fig. 1 showing the supplement in position;

Fig. 4: a detail perspective view of the supplement; and

Fig. 5 a fragmentary end view partly in section of the bookwith the supplement in place.

Referring to the parts by numerals, 1 and 2 designate the cover members of the book and 3 designates the back. A body of leaves 4 are permanently bound to the back in the usual manner. The back is made wider than the thickness of the body of leaves in order to provide a space between the said body and the cover member 2 to receive a removable supplement 5. Extending forwardly for a slight .distance from the back of the book in the space between the body of leaves and the cover member 2 is an abutment stub 6. This stubis'formed of a body of stub leaves 7 and a fabric binding strip 8. In the menuthe covers are bound to the back of the book in the usual manner. A desired number of theleaves adjacent the cover member 2 are then severed on a line extending parallel to the back and a short distance therefrom. The severed portions of the leaves are next removed leavin the stub leaves. The stub leaves are there ore bound to the back along folded and lapped upon itself as at 9 and 10 and is secured to the adjacent main leaf as at 11 and to the inner side of the cover member 2 as at 12. Throughout its whole area of contact therewith the fabric strip is pasted to the stub 6, the cover 2 and the body of leaves 4. The stub leaves are thus bound together to form a body and their forward edges are protected'by the fabric.

The cover 2 has a layer of material 13 secured thereto at the forward andv side edges of the cover. This layer 13 extends rearward] to a point adjacent the forward edge of t e abutment stub and forms with the inner face of the cover 2 a pocket which opens toward the stub. The supplement 5 is formed of a body of leaves bound to a cover 14 preferably of stiller material than the leaves. In placin the supplement within the book one of t e members of its cover 14 is. inserted within the said pocket upon the cover member 2, as shown in Fig. 3, and the back of the supplement is pressed against the end of the abutment stub 6. The walls of the pocket fit the inserted cover member of the supplement snugly and serve to frictionally hold it and retain the supplement in place within the book with its back or folded edge abutting the stub and its edges true with the edges of the main leaves of the book. It will be understood that the abutment stub may be formed in other ways and secured within the book in a difierent manner from that shownand described.

The leaves of the supplement are sli htly narrower than the leaves of the main lied of the book but they are substantially of the same length so that when the su plement is in place the ed as of the leaves 1; ereof are flush with the edges of the leaves back, so that when the supplement is secured in place and the covers are closed it will be practically impossible for the supplement to shift and get out of line with the main body of the leaves even though the book be roughly handled.

The edges of the leaves in the stub are exposed at the ends of the stub and these exposed edges are flush with the corresponding exposed edges of the leaves of the main body of the book. The advantage of this is that when the supplement is in place and the book covers are closed the entire book has the appearance of a completely bound book without a supplement. The break in the leaves between the ends of the stub leaves and the inner bound edge of the supplement is not noticeable due to the fact that the edges of the stub leaves are exposed and that the stub leaves are bound as a part of the bound book and that their exposed edges are trimmed flush with the exposed edges of the leaves of the main body of the book. The su plement is preferably substantially as thic as the abutment so that when a supplement is in place the book covers will be substantially parallel with each other.

From the foregoing it will be seen that I have provided a book that is extremely simple and requires only very slight additional work in its manufacture over the manufacture of a book of standard form. The book presents a neat, clean-cut appearance either with or without the supplement inserted. When the supplement is inserted there is no bulging of the cover members or back of the book and when it is removed there is no slack in the binding. The abutment stub in combination with the pocket serves to acbook is closed the back will be maintained rigidly in its proper form regardless of whether or not the supplement is inserted, and the stifi back structure will hold all of the edges of the book true.

What I claim is: p

In a book the combination of a back, a pair of covers flexibly connected to the said back, a compact body of leaves permanently secured to the said back and completely and solidly filling the back from cover to cover said leaves being in contact with each other and rigidly supporting the back throughout its entire area and rendering the back rigid to resist lateral compression some of said leaves forming the main body of the book and some of said leaves being short and extending a short distance outwardly from their point of attachment to the back to form a short abutment stub extending the full length of the back adjacent one cover member and adapted to contact with said cover member along its flexible connection with the back, the main bod of the book and the abutment stub maintaming the back of the book at a fixed width the edges of the leaves at the ends of the stub being exposed and cut flush with the edges of the leaves of the main body of the book, a permanent fabric binding covering and securing together the forward edges of the stub leaves, a supplement having a body of leaves smaller than the leaves of the main body of the book and having a cover member said supplement having a bound ed e in contact with the free inner edge 0 the abutment stub and the free edges of its leaves flush with the edges of the leaves of the mainbody ofthe book, and means for removably securing the supplement cover to the book cover.

In testimony whereof I hereunto aflix my signature.

WILLIAM E. BALDWIN.
